Sloan Upstate constructs highway and commercial projects, all of which vary in size from large parking lots, industrial plant expansions, to interstates and airports. We take pride in knowing that the construction services we offer our customers are of the highest quality and will meet or exceed the owner’s expectations and schedule.


Sloan leads the way in Safety, Quality Workmanship, and Innovative Civil Construction Practices. We accomplish this through interactive training of our employees at all levels through The Roads Academy. We focus on various practices including manufacturing asphalt mix, placing product, operating machinery, estimating, accounting, human resources, project management, and risk-management through safety. Our program’s slogan is “Building Better Roads & Bridges… One Employee at a Time.”
